It's more intuitive to specify needed MTU sizes instead of raw buffer
sizes. The exact buffer size calculations can instead be made
internally in the code (using the BT_L2CAP_BUF_SIZE helper macro).

We know the needed values at build-time, so there's no point in having
a runtime mechanism of accessing them in the code. Having the values
as defines makes it e.g. possible to use them as input for defining
the size of buffer pools.

The space that the HCI driver needs to reserve for its own use is not
necessarily symmetrical. E.g. even with the current H4 driver we only
need to reserve space for sending data but not for receiving it.
Keeping track of these values independently enables more efficient use
of the buffers.

According to the Core Spec we shall respond to Exchange MTU Request
with MTU parameter set to the maximum MTU that we can receive.
As a Client, we shouldn't send an error if Server's Rx MTU exceeds
517 bytes. Whe should respond with our maximum MTU, because
after negotiation is done, ATT_MTU shall be set to the
minimum of the Client Rx MTU and Server Rx MTU values.
Error will be sent only in case of Rx MTU lower than LE default
ATT_MTU (23).

Modifies ATT transport bt_att_read_mult_req type used in read multiple
request.
Internally now it's been declared as array of handles.
For ensuring validness of minimum PDU length being 4 octets wide for
multiple read request, new define is introduced and used instead of
type sizeof evaluation.

This adds bt_att_send which will be used by GATT client API to send
requests.
Note: bt_att_send can only handle one request at time but once the
requirements are clarified it will probably be extended to support
more requests to attend multiple applications probably using a fifo.
